I replaced a Haffler 220 amp with a Stratos in a friend's system (McIntosh 2200 preamp, B&W Matrix 805 speakers). The difference was remarkable - more detail, more control, more solid bass, better imaging. I guess my experience was different from Hammergjh's.
Halo or Odyssey
Opinions Please! Speakers are VMPS Super Tower/R's with newly updated drivers, driven via PS Audio 4.5 Preamp/Hafler DH-220 power amp. Considering an ugrade too new components without breaking the budget. I am wondering which would be a better solution, the Halo P3/A23 or the Odyssey Tempest/Stratus? Or should I just keep the PS and Hafler until they expire? The sound they produce is still quite satisfying. Thanks for your time and help.
